Document Type and Number:
WIPO Patent Application WO/2022/050562
Kind Code:
A1
Abstract:
The present invention relates to a wire saw for an excavator, wherein the wire saw is configured to be rotatable by 360 degrees, and a wire saw body can be rotated and used through a link even after the wire saw is mounted on the excavator, whereby it is possible to reduce a separate working time required for the reinstallation of the wire saw and smoothly cut a rough stone. Particularly, the wire saw comprises: a body (110) having multiple support protrusions (111) on the bottom thereof so as to be firmly supported on a rough stone to be cut; an arm (120) formed to perpendicularly protrude from the front end of the body; a fixed pulley part (130) installed at the lower end of the arm by a support piece (132); a movable pulley part (140) formed at the front end of the arm so as to move up and down along the arm; a rack (151) provided along the vertical length of the rear end portion of the arm (120); a driving part (150) for moving the movable pulley part (140) up and down in conjunction with the rack; and a link part (160) which is formed at the rear end of the body (110), is connected to the arm of the excavator, and is rotatable by 360 degrees.
